UIManager.put("ProgressBar.background",Color.YELLOW);
UIManager.put("ProgressBar.foreground",Color.RED);

Make these the first lines in your main method. Essentially this should be defined before you create any progress bar objects.

but we are not mentioning any object reference to progressBar instance.
How UIManager going to understand which object it should refer ?

the solution you've given is working

Check out the source code for the BasicProgressBarUI and see where and how it uses these properties.
The source code can be found in a file called src.zip in your java installation directory

Is it?
Now add UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); before you create the UI and see what happens

[swapnel surade]

  UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());  

this snippet applies the system level UI changes to application.

is there any way to change the shape of the progress bar box.

In that case you need to overrite your own basic progressbar ui so that while painting it will under go and draw how we have specified.
